I bought the Milwaukee and kinda regret it. I think I would have been happier with Makita.
I think you know this about me: I think most tool reviews are ****. Tool reviews quickly became tool sales or YouTube businesses such that its tough to actually get someone with actual hands on experience using the tool.
Anyway, I bought that saw like a year ago or so and have used it pretty extensively. 2 things I don't like about my Milwaukee Track saw:
1) It needs batteries bigger than any of my other Milwaukee tools need. Therefore, the saw doesn't/can't use a common M18 battery. I have a few Milwaukee tools and none of them share batteries with the saw. I think the 2 smaller batteries on the Makita solves that.
2) The Milwaukee blades aren't great. And that's the business end of the tool. Makita uses Tenryu blades which are top notch. And the way their blades are, you can swap them for Freud/Diablo blades, which I like. Milwaukee can't. The blade thicknesses and kerfs don't allow brand swapping (or I'd cut the fence rubber or have a gap). The other related problem is the thickness of the riving knife. Technically I could take it off I guess.
Regarding track saws: I used mine for the last 3 days straight- almost all day long. Today, I had this sort of epiphany: I do what I do, I make my cuts, then the track goes away, saw goes on a shelf under the work bench, and all my stock is there on my clean work bench ready for the next step. My saw station is my workbench. And all the stuff I need is right there. I don't move lumber to another place, an assembly table or whatever. It's convenient to just have a work bench where you do all your work.
This is an old picture, but I'm building the last 4 windows for the 3rd floor of my next house (barn conversion). I saw up Azek to make cpvc frames for 120yr old window sashes. I do the whole job including painting at this one work bench. At the left end of the bench, I drilled a hole for a router and made a fence out of scrap Azek.
I just hold it in place with C clamps at each end. The MDF could be waxed or finished to make a lower friction surface. The Azek is ok- not as good as UHMW, but this was scrap I had on hand.
Here's the cut-out for the router bit on the other side.
